Frequently Asked Questions
What does a VIN-programmed TCM actually mean?
It means we load your vehicle’s unique Vehicle Identification Number (VIN) and the latest GM software onto the module before it ships. This allows it to communicate perfectly with your vehicle’s engine computer and other systems, just like the original part. No additional programming or dealer visits are required.
Is this a difficult part to install?
For most DIYers with basic tools, this is a straightforward installation. The TCM is typically located in the engine compartment and can be replaced in under 30 minutes. Just disconnect the battery, unbolt the old module, disconnect the wiring harnesses, and install the new one in its place.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause, it’s essential to have the specific transmission codes (e.g., P07xx) read to confirm. This programmed 24239926 TCM is the direct solution for many of those underlying codes.
Do I need to send my old part back?
No. We do not require a core return for this part. You can keep or dispose of your old module without any additional hassle or charges.
How do I ensure this fits my exact vehicle?
This T42 TCM fits a wide range of 2006-2014 GM vehicles. The best way to confirm is to match your original part number to one of the interchange numbers listed in the description (like 24252114, 24234503, etc.) or use our website’s vehicle selector. Providing your VIN during checkout guarantees we program it correctly for your specific application.
